11. The set {f, f2, . .., fn} where each fk is a real-valued function defined on R, is said to be linearly independent if c1, C2, . .. , Cn E R and E C fk (x) = 0 for every r ER implies C1 = c2 = ·..= Cn = 0 Suppose fr(x) = x* for all x ER and k = 1, ..., n. Then, A. the set {f1,..., fn} is linearly independent. B. each pair of these functions is linearly independent, but larger n-tuples are not. C. only the subset of odd-numbered functions and the subset of even-numbered functions are linearly independent. D. every "proper subset of this set of functions is linearly independent, but the whol
Rate of Change
The relation between two quantities which displays how much greater one quantity is than another is called ratio.
Slope
The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:
The question is attached in the image. How can a function defined in the following manner be 'linearly' independent? The function is given by "fk (x) = x^k". For any x value we can define a transformation in this manner but why will the set be 'linearly' independent?
Please provide a solution for the question given in the image. Thank you.
